Fig. 4: Transient absorption spectra of the α-Fe2O3/Al sample.

From: Time-resolved chemically-selective spectroscopic investigation of the redox reaction between hematite and aluminium

Fig. 4

Transient absorption (TA) spectra at some representative delays for Fe M2,3-edge of hematite (a) and Al L2,3-edge of aluminium (b). The flexible sigmoid function used for the fits is reported in the SI. For the Al TA, the difference between two sigmoid functions has been employed for the fitting. Error bars are calculated using Eq. 5 in the Supplementary Information. Source data are provided as a Source Data file.
